> 1. Does Labview (or can I make it) keep all the past versions? Labview can do virtually anything, you just need to wire it all up. :-)
If this is a problem without upper bounds (...<b>all</b> the versions ..), you might just append all changes to a datalog file. Each record could be a cluster of e.g. timestamp and your panel item. To retrieve an entry, you just read the desired record from the file. You don't need to worry interpreting the binary data, just read it back into an item with the same structure.
